RCT in India with low risk patients, comparing 24mg ivermectin, 12mg ivermectin, and placebo showing non-statistically significant improvements in recovery and PCR+ status (day 5 both arms, day 7 24mg only) with treatment, and showing greater improvement for the higher dose arm. Viral load decline was similar in all arms - absolute values are lower for ivermectin in a dose-dependent manner, however the baseline value for the ivermectin groups was lower, leaving less room for change. There were no deaths or use of mechanical ventilation. There were no serious adverse events. Note that our pre-specified protocol prioritizes clinical outcomes over PCR results.
Viral load measured by PCR may not accurately reflect infectious virus measured by viral culture. Porter show that viral load early in infection was correlated with infectious virus, but viral load late in infection could be high even with low or undetectable infectious virus. Assessing viral load later in infection may underestimate reductions in infectious virus with treatment.
This is the 16th of 46 COVID-19 RCTs for ivermectin, which collectively show efficacy with p=0.00000014.
This is the 35th of 99 COVID-19 controlled studies for ivermectin, which collectively show efficacy with p<0.0000000001 (1 in 2 sextillion).
